Re: One last try before I literally shoot my pi 3

 

George,

Thanks for your interest in how I run my Pi's. For an overview of my two main setups, here is an article I wrote about them. This article is about my first Pi setup. My second Pi setup is the same but permanently?built into my Jeep:


To this day they both run on a Pi 3B+ that run on the Buster operating system. More on that later. Also they are not set up to run VARA since the 3B+ doesn't seem to have enough horsepower for it. Also I have not overclocked either of these Pi's.

As you can see in these two builds in particular it's more conducive to use a Pi instead of going to a laptop - just my opinion.

As stated in the article, all of my Pi's run headless and I use VNC with an iPad to run them. One thing I have found when running VNC on a Pi. I set the "picture quality" to LOW on my iPad inside VNC so when it connects to the Pi, there doesn't seem to be as much cpu usage while the Pi is sending the screen to my iPad. Doing this seems to help the performance of the Pi.

As far as operating systems go, Bookworm seems to consume more cpu than Buster which is why these two systems have stayed on Buster.

Sometime after this weekend (its Winter Field Day weekend) I plan on looking into using a Pi5 for these two systems. BTW, I will be using the setup in the article above.

Now concerning VARA, like I said earlier, the two systems discussed I don't run VARA. The one system I run VARA on is a Pi4 / 8 GB that is overclocked to 2.1 gHz. It runs an Icom IC-718 and is a lowband?only setup so I can't comment on the VHF side of VARA.

Yes, VARA is a bit sluggish for me too and obviously using a laptop without VNC would be more robust, but again the two things that helped me the most are the overclocking and the setting of the VNC picture quality to low.

Concerning SD cards, I only use SanDisk ImageMate Pro. There might be better ones, I don't know, but these work for me. I don't use an SSD at all.

Concerning APRS / Pat / Xastir etc. they all work fine for me including?on my Pi Zero. But then that is running Buster - esp. on the Zero.

OK sorry for the long post, I hope I have answered everything George.

All my PIs are stock. I run VARA on both the 4GB and 8GB Pi 4 with no problems or hangups. I also use an SDR with them and use OP25 for trunking scanning of our statewide public service network as well .The biggest issue is the choice of OS. I'm a few versions behind current and have tried the different versions as they've come out but I primarily still use Buster. That limits me from some new things but I have no bugs and everything works fine.

Mike:
Very interesting all about your PIs. May you share something about the performance when using VARA HF or FM with your Rpi4?? Something about the disk used to get an aceptable performance (micro SD disk or SSD)? And using YAAC for APRS or any map with GPS?
Anything related to the performance with your RPIs with SDR.
?
In my case I have tried micro SD and SSD and the performance is not acceptable, I have not tried yet to overclock.
?
I have all in RPI 4B 8Gb: Fldig, Pat Winlink, Vara, YAAC, SDR Plus, I want all in one for HF, APRS 2M.? But very frustrating to use pat and Vara slow moving for typing, or interacting.

Near to get it to simple tasks for may RPI 3, and 4 an go to a laptop with Linux. But I have to say I like lean working in everything and take at the most everything compress and all in one or two.
